Need Help? The axle is rated based on the lowest capacity component fitted to that axle. The installer should check that the tire and rim combination meets the load requirements. The rating information on the Hendrickson vendor provided hubs can be found at:. For KIC wheel ends standard fit : www. A non-steerable lift axle that is not raised when turning, especially in a tight corner, will scrub concrete and impose high lateral stress on the wheels and chassis components of your vehicle.

Preventive Maintenance. Load Sensing Valve. The conventional trailing arm suspension 14 is mounted in tandem with a liftable suspension of similar construction. Electro Pneumatic Handbrake Modulator. Alternatively, the first suspension can be a mechanical suspension, such as a leaf spring, and the means to detect the load on the first axle can be a strain gauge. For comparative purposes, the relatively short period of time in which the override means is operative is substantially longer than the time delay for operation of the actuation means. Conventional Braking Components Hose Coupling. Product changes may have been made after the copyright date that are not reflected. The control valve 60 has a normally closed inlet port connected to pipe 68 which is connected to coupling 52 for supply of air pressure to the control valve Hydraulic Brake Chamber. If the pressure switch is very sensitive to this small change in load in the axle 26, then the lift axle would be immediately raised, at which time the load would again exceed the predetermined value. In operation, when the toggle switch is in the open position, as illustrated in FIG. Air Dryer - Single Chamber.

Fittings Single Fittings. Fixed Caliper Disc Brake. However, in the event that the load changes from below the predetermined value to above the predetermined value, there is a time delay TD PS , which must occur before the transistor will be switched off to block current flow to the solenoid Hydraulic Engine Brake. Thus, in the event that the pressure sensed by the pressure switch is above a predetermined value, the switch will open to prevent any further current flow through the transister Q1 after the timer TD S is timed out. Each AIRman product is designed to meet or exceed OEM standards and meet the widest range of temperature, chemical resistance, sludge and lifecycle performance. A control system according to claim 2 wherein said second suspension comprises an air spring for cushioning said second axle with respect to said vehicle frame and an air cylinder for actuating the raising and lowering of said second axle with respect to said frame; said control means further comprising means to release air from said second suspension air spring and simultaneously to pressurize said air cylinder when said second axle is moved between said lowermost position and said raised position. IC1 performs the timing functions described above with reference to FIG. Adapting Valve. When the switch is closed, the liftable axles are raised so that the wheels attached thereto are out of contact with the road. Don't have an account yet? Need Help? Automatic control of the lift axle is provided through a pneumatically operated valve which senses the pressure in the down axle air spring.
